PYROPHOROUS GAS-LIGHTER.

Specification of Letters Patent.

PatentedJune 9.19114.

App1ication filed 0ctober28; 1913. SerialNo. 797,771.

To all whom it may concern Be it known that I, JACQUES KELLERMANN, asubject of the German Emperor, and residing at 114 Kopenickerstrasse,Berlin, S. O. 16, Germany, have invented certain new and usefulImprovements in Pyrophorous Gas- Lighters, of which the following is aspecification.

The presentinvention consists of a :pyrophorous gas-lighter with meansfor fixing it, which are so constructed, that the gas lighter may befitted by any one to gas lamps, without the need of any special tools orother contrivances.

The gas-lighter further comprises a wall covering the sparks produced bythe pyrophorous material, which wall will conduct the sparks over theupper edge of the gas lamp to be lighted, so that the said sparks willpositively meet the gas rising from the lamp, and ignite it.

The gas lighter is operated by means of a rocking lever under action ofa spring, by the rocking of which the frictional member is operated,whereby the spark is produced.

In the accompanying drawing Figure 1 is a gas lamp which is fitted withthe pyrophorous gas-lighter. Figs. 2 and 3 are broken side views of thegas-lighter in two different positions and Fig. 14 is a cross sec tionon the line IV-IV of Fig. 2. Figs. 5 and 6 illustrate a modification ofthe arrangement shown in Figs. 2 and 3.

The gas lighter consists of a casing 1, which has at its upper edge ahook-shaped nose 2. Another hook 4 is attached to a spring 3 secured atone end to the said casing 1, and by means of these two hooks the casingcan be attached to the gas lamp. In the embodiment shown in theaccompanying drawing the gas-lighter is shown fitted to aninverted gaslamp, the hook 2engaging over the top rim 5 of the burner casing, whilethe hook4 at the free end of the spring en-1 gages over the lower rim orin one of the perforations which are generally found in such burners. Bymeans of the tension of the spring 3 between the said two hooks thegas-lighter can readily and without any further instruments be attachedto any such gas lamp. The casing 1 is further preferably provided belowwith an extension 6, which serves as akind of support, bearing againstthe body of the lamp. On the top ver into its upper position, when ithasbeen moved downward in the direction of the arrow I .(Fig. 1). A nose14 of the lever 12 engages behind a pawl 15 on the file 10. When,therefore, the lever 12 is rocked the file will be moved by means of thenose 14- and thepawl 15, as shown in Fig. 3, until the nose 14 isdisengaged from the pawl 15, and the latter is released whereupon thefile 10 can swing back in the direction of arrow II, Fig. 3. When thelever 12 is again released its nose 14 will strike against the pawl 15,which is under action of a spring. and is thereby swung back, so thatthe nose 14 can pass whereupon it reengages behind the returning pawl 15as shown in Fig. 2.

In order to positively conduct the sparks into the path of the ignitiblegas current rising fromthe lamp, a wall 16 is provided above the hook 2,by which wall the sparks produced by the file are made to pass over theupper edge 5 of the gas lamp. At the.

same time this wall 16 will catch a part of the rising gas and conductit toward the sparks. The wall 16 thus together withthe guide 9 and thefile 10 forms a guide passage for the sparks.

In Figs. 5 and 6 the pawl 15 in Figs. 2 and 3 has been replaced by :1lug 18 eccentrically bored and pivoted at 17. This lug 18 has such ashape, that it, and with it the file 10, is dogged by lever 12, andafter clearing the lever 12 it returns and allows the arm 14 to pass,thereupon returning by its own weight into its position of rest. By thisarrangement the auxiliary spring of pawl 15 in Figs. 2 and 3 isdispensed with and a re liable operation of the device is insured.

I claim:

1. In a pyrophorous gas lighter means for readily attaching it to a lampand detaching it therefrom, said means consisting of a hook fitted tothe body of the lighter and adapted to engage over the top rim of thelamp, a second hook adapted to engage below with the lamp, and anelastic ,m mber between said hooks;

2. In a pyrophorous gas lighter means for readily attaching it to a lampand detaching it therefrom, said means consisting of a hook fitted tothe body of the lighter and adapted to engage over the top rim of thelamp, a second hook adapted to engage below with the lamp, and anelastic member between said hooks, on said body of the lighter and atits lower end a bracket adapted to bear against the body of the lamp andact asa support for the lighter.

3. In a pyrophorous gas lighter'means for readily attaching it to a lampand detaching it therefrom, said means consisting of a hook fitted tothe body of the lighter and adapted to engage over the toprim of thelamp, a second hook adapted to engage below'with the lamp and an elasticmember between said hooks, over the saidupper hook a wall projectingbeyond it and adapted to act as a baffle for the sparks and conduct theminto the current of gas rising and also 1 Copies of this patent maybeobtained for five cents each, by addressing the Commissioner of Patents,

to baffle the said rising current of gas to= ward the sparks.

4:. In a pyrophorous gas lighter means for readily attaching it to thelamp and detaching it therefrom, said means consisting of a hook fittedto the body of the lighter and adapted to engage over the top'rim ofthelamp, over the said upper hook a wall pro ject-ingbeyond it and adaptedto act as a baflie for the sparks and conduct them into the current ofgas rising and also'to baffle the said rising current-of gas, a frictionmember moving in aguide arranged beneath and in the direction of thesaid baffling wall and forming with said walla guide channel for thesparks.

In testimony whereof I hereunto set my hand in the presence of twowitnesses.
